DM-GS35WU255001P30DF-11 provides controlled 250–260 nm deep-ultraviolet emission for disinfection, sterilization, purification, optical sensing and bio-analysis systems. Its eutectic 3535 SMD construction supports compact optical assemblies and reliable thermal integration.
Integration and Safety
- Use a regulated constant-current driver and observe all specified current and voltage limits.
- Provide adequate heat dissipation and ESD protection during assembly.
- UVC radiation can damage skin and eyes; use shielding, interlocks, protective clothing and UV-rated eye protection.
- Verify thermal and optical performance in the finished equipment before production release.
